Split King Delivery & Setup: Your Complete Guide

Written by: Matthew Timmins, Founder and Managing Director, Leva Sleep

Key Takeaways

A split king arrives as multiple separate components, including two Twin XL mattresses, two adjustable bases, legs, remotes, and hardware that all need assembly.
Measure wall width, doorway clearance, stairwell dimensions, and walking space before ordering to avoid delivery-day surprises.
Choose between DIY threshold delivery or white-glove setup based on access, physical capacity, and how much the first-night experience matters.
Prevent base drift, center ridges, and sheets popping off by joining bases, matching mattress thickness, and using split-king-specific bedding.
Leva Sleep provides in-house white-glove delivery, matched split-king systems, and bedding engineered for adjustable bases to support a smooth first 30 nights.

What Actually Arrives On Delivery Day?

A split king arrives as a collection of components that must be staged, assembled, and connected before the system works. A typical split king shipment includes:

Two Twin XL mattresses, each in its own box or roll-pack
Two Twin XL adjustable bases, each in a separate compressed box
Leg sets for each base, usually adjustable-height segments
Two remotes or one remote per side, plus any sync or split-king connector hardware
Two power cords and any Bluetooth pairing hardware
A QR code on each base box linking to assembly instructions

Weight matters because it determines how many people you need on delivery day. A split king setup delivers roughly 86 lbs of mattress across two separate boxes. Adjustable bases vary significantly by model, and a Twin XL base can weigh 108–113 lbs depending on the manufacturer. A complete split king with two mattresses and two bases can arrive as more than 400 lbs of boxed components before legs, remotes, or accessories are counted.

Plan for staging space. Each base box is large enough that two of them can fill a standard bedroom doorway before assembly begins. Clear the room, the hallway, and the stairwell before the truck arrives. Most adjustable bases ship in a compressed box and include a QR code linking to assembly instructions.

How To Check Room Fit And Access Before Ordering

Many split king regrets start with access problems, such as a base that will not clear the stairwell or a 76-inch footprint that leaves no walking space. These checks need to happen before you place the order.

Wall footprint. A split king occupies 76 inches of wall width. A standard king mattress provides 6,080 square inches of sleeping surface and is 16 inches wider than a queen. Couples who cannot fit a 76-inch footprint can consider Leva Sleep’s Split Queen adjustable beds, which include five packages from $1,399 with 30″ × 80″ mattresses Leva manufactures itself and a full line of Split Queen bedding.

Doorway clearance. A standard US bedroom door with a nominal 32-inch slab provides a clear opening of only about 30 to 30.5 inches once the door leaf and stop are accounted for. A Twin XL base box is wider than that. Removing an interior door at the hinges typically reclaims two to three inches of clear opening and often provides the fastest fix for a tight doorway.

Stairwell and landing. Measure stair width between walls or railing, ceiling height above the treads, and landing depth at any turn. A base box that clears the door may still not rotate around a switchback landing. Share these measurements with the delivery crew before the truck leaves the warehouse.

Walking space. The Sleep Foundation recommends leaving around 24 inches of space between the bed and surrounding walls or furniture. In a room smaller than 12 × 12 feet, a 76-inch split king can leave less than two feet of clearance on each side.

Two-person lift. Standard adjustable base installations with legs typically take 30 to 60 minutes, and most of that time goes into lifting the base into the frame, which is why two people are recommended. A Twin XL base weighs 110–150 lbs depending on the model, so a solo setup is realistic only for zero-clearance configurations that do not require lifting. Split configurations help because each half is smaller and more manageable than a single king base.

DIY Split King Setup Vs. White-Glove Delivery: Choosing Your Path

Split king buyers follow one of two paths: DIY threshold delivery or white-glove delivery and setup. The right choice depends on access, physical capacity, and how much you value a frictionless first night. The table below shows what each option includes, who does the work, what you must provide, and how costs typically behave.

Delivery Type	What's Included	Who Does The Work	What You Supply	Cost Notes
DIY / Threshold Delivery	Boxes delivered to front door, side door, or garage. No in-home carry, no assembly, no old-bed removal.	Buyer and a helper	Tools, a second person, staging space, old-bed disposal	For OCOCHI bed frame orders, threshold delivery to the inside front door or garage is included free. Assembly, packaging removal, and stair carries are not included and remain the buyer's responsibility.
White-Glove Delivery And Setup	In-home carry to the bedroom, full assembly, leg height adjustment, mattress placement, old-bed removal, system walkthrough with both partners.	Trained delivery team	A clear path and a decision on leg height before the team arrives	Varies by retailer; available for a fee at Leva Sleep, with current pricing listed on the Leva Sleep site.

Leva Sleep provides in-house white-glove delivery and setup, including removal of the old bed, full assembly, height adjustment, and a walkthrough of the system with both partners. Leva’s own trained team performs this work instead of a third-party freight contractor, so the crew that arrives knows how to pair remotes, set leg height, and sync both sides before leaving the room.

How To Set Up A Split King Bed

This sequence walks through a DIY setup. White-glove customers can use it as a checklist to confirm the team completes each step correctly.

Clear and measure the space. Remove the old bed entirely. Confirm the 76-inch wall width, the walking clearance on each side, and the ceiling height at the top of any stairwell. Mark the final position of each base half on the floor before unboxing anything.
Unbox and stage components. Open each base box in the hallway or a staging area. Lay out legs, remotes, power cords, and sync hardware before moving anything into the bedroom. Confirm all parts are present against the packing list.
Assemble each base and attach legs. Follow the QR-code instructions for each base independently. Attach legs at the specified height, which often includes settings such as 3, 6, 9, or 12 inches, though increments vary by manufacturer. When you finish, the base should sit level on all legs with no wobble.
Position the two halves and join them. Carry each base into the bedroom and place it inside the frame or against the wall. Align the two halves so the center gap is even and both bases are flush at the head and foot. Attach any joining bracket or strap supplied by the manufacturer.
Place the two Twin XL mattresses. Set each mattress on its corresponding base. Confirm the mattresses are flush at the head, foot, and center. Misalignment here creates a center ridge that worsens over time.
Connect power and sync cables. Plug each base into a dedicated outlet. Connect any sync cable between the two bases if the manufacturer supplies one. Both bases should power on with no error lights.
Pair the remotes and app, then test articulation. Follow the manufacturer's pairing sequence for each remote or app channel. Test head and foot articulation on each side independently. Both sides should reach full elevation and return to flat smoothly and quietly, with each remote controlling the correct base.

Those steps assume the mattress and base are designed to work together, which is where matched systems like Leva Sleep's Duet Split King Adjustable Bed come in. Leva mattresses are engineered to flex with the base rather than resist articulation, which often shortens the life of third-party mattresses placed on adjustable bases. Higher-end Leva bases include full app control via Bluetooth, custom sleep positions, vibrating alarms, and anti-snore micro-adjustments.

How To Keep The Two Halves From Drifting Apart

Base drift is the most common complaint in the first 30 nights of split king ownership. It happens because two independent bases sit on a shared floor or inside a shared frame with no rigid connection between them. Every time a base articulates, it exerts lateral force, and over hours of use the halves migrate apart.

The practical remedies, in order of effectiveness, include:

Joining brackets. Many manufacturers supply a bracket that bolts the two bases together at the head and foot. This option usually provides the most reliable fix and should be the first thing you check in the box.
Straps or zip ties. A heavy-duty strap looped around both bases at the center provides friction resistance without a rigid connection. This approach is less permanent than brackets but effective for bases that drift slowly.
A shared bed frame. A king frame with an open interior and no center rail contains both bases and limits lateral movement. A split king frame requires an open interior with no fixed center support rail, because a center rail would block the articulation of one or both Twin XL bases.
A bridge connector. The 1- to 2-inch center gap between the units can be bridged with a split king bridge connector available from bedding retailers. A bridge fills the gap at the mattress surface level and reduces the sensation of separation without mechanically joining the bases.

Some movement between the two halves is normal in any split configuration, so the goal is alignment rather than rigidity. Locking the bases together completely can transfer vibration from one side to the other, which defeats the purpose of independent bases.

How To Re-Pair Remotes And Apps After A Power Interruption

Each side of a split king typically has its own remote or app channel. Sync can be lost after a power interruption, a tripped breaker, a battery change in the remote, or a Bluetooth dropout. The general re-pairing sequence is:

Confirm both bases are fully powered. Check that the power cord is seated at both the base and the outlet, and that the outlet has power.
Put the base into pairing mode per the manufacturer's instructions. This usually involves holding a button on the base or the remote for three to five seconds until an indicator light flashes.
Re-pair the remote or app to the correct base. On a split king, pair the left remote to the left base and the right remote to the right base before testing.
Test head and foot articulation on each side independently. Confirm the left remote controls only the left base and the right remote controls only the right base.
If the app loses connection, delete the device from the app's paired list, restart Bluetooth on the phone, and re-add each base as a new device.

Clinicians commonly recommend sleeping with the head elevated for conditions including sleep apnea, acid reflux, and post-surgical recovery. An adjustable base is how that position is achieved at home, night after night, without stacking pillows, so a working remote becomes essential. If re-pairing fails repeatedly after power interruptions, contact the retailer, because repeated sync loss can indicate a firmware issue or a failing motor controller. For snoring relief specifically, Leva Sleep's snoring relief collection pairs the right base with the right mattress for consistent anti-snore positioning. Remote sync is only one of several issues that surface in the first month; the rest tend to be physical problems with the bed itself.

Common Split King Problems In The First 30 Nights

Center ridge. A ridge at the center of the bed appears when the two mattress halves differ in thickness, firmness, or both. Matching mattress thickness across both halves and using a bridge connector at the surface level usually resolves this. A mattress protector that spans both halves can also reduce the tactile sensation of the gap. If the ridge persists after 30 nights, the mattresses are likely mismatched and one or both should be exchanged.

Sheets popping off at elevation. Standard king sheets are cut for a single 76-inch mattress. On a split king at elevation, the fitted sheet must stretch over two independently articulating surfaces, so it tends to pop off the corners. Twin XL sheets fit each half individually but leave the center gap exposed. Leva Sleep designs its bedding specifically for split and adjustable beds, with extra-elastic fitted sheets, deep pockets, duvet clips, and remote pockets available in both Split King and Split Queen configurations.

Persistent motor noise. A whisper-quiet base that develops noise after delivery may have a loose leg, an unlevel floor contact, or a motor connection that was not fully seated during assembly. Check all legs for tightness and confirm the base sits level before contacting the retailer.

When to call the retailer. Contact the retailer for persistent motor noise that does not resolve after leg and connection checks, a base that will not articulate past a certain angle, repeated remote sync loss across multiple power cycles, or a center ridge that does not resolve after 30 nights with matched mattresses and a bridge connector. For pain relief support, Leva Sleep's best-for-pain-relief collection is a useful starting point for couples whose setup decisions are driven by back, hip, or joint pain.

Why Leva Sleep Excels At Split King Delivery And Setup

Leva Sleep operates as a specialist adjustable bed company rather than a generalist mattress retailer, and that focus shows up on delivery day and in the first 30 nights.

Leva offers 15–20 adjustable base models, compared with 3–5 at a standard retailer. Complete adjustable bed packages run from $1,299 to $8,999+. Financing is available, including 0% APR options. Leva Sleep's stated policy is a 180-night comfort guarantee, though the US store currently displays a 60-night guarantee, so the setup decision does not lock you in on day one and adaptation to a new sleep surface and position takes weeks.

Leva carries Aireloom, Tempur-Pedic, Stearns & Foster, Beautyrest, Serta, Kingsdown, and Helix, and pairs each brand with the right base. Leva Sleep mattresses are made in the US, and 50% of the US lineup is unique to the American market, including premium California-made brands. Leva has operated for nine years and served more than 25,000 customers, so the current split king system reflects years of iteration rather than a first-generation experiment.

The La Jolla showroom exists because this is a product that benefits from lying down on it. A ten-minute conversation with a specialist and five minutes horizontal on the actual system often provide more clarity than hours of online research. For couples who have already decided on a split king, the Duet Split King Adjustable Bed is the place to start. That matters because the problem these beds solve is widespread: a 2025 survey of more than 2,000 US adults conducted by Atomik Research for the American Academy of Sleep Medicine found that 31% of American adults have opted for a "sleep divorce," rising to 39% among adults aged 35 to 44. A further 37% of US adults go to sleep at different times to accommodate a partner. A split king adjustable bed set up correctly, with matched mattresses, joined bases, and bedding that stays on at elevation, helps many couples stay in the same bed without forcing either partner to accept the other's position.

Frequently Asked Questions

Can You Feel The Split In A Split King?

Most couples feel the center gap initially, particularly when lying directly in the middle of the bed. The gap between two Twin XL bases is typically 1 to 2 inches. A bridge connector at the mattress surface level reduces the sensation significantly. Matching mattress thickness across both halves and using a split king bridge eliminates most of the tactile difference within the first few weeks. Couples who sleep primarily on their own side of the bed rarely notice the split at all after the first month.

Do You Need Two People To Set Up A Split King?

For a DIY setup, two people are strongly recommended. As noted earlier, each Twin XL base weighs over 100 lbs and must be lifted into the frame and positioned precisely. Attempting a solo setup on a staircase or in a tight hallway creates a real injury risk. White-glove delivery removes this risk because the trained team handles all lifting, positioning, and assembly.

What Sheets Fit A Split King Adjustable Bed?

Standard king fitted sheets do not stay on a split king at elevation. The correct solution is Twin XL fitted sheets on each half, which fit each base independently and stay on through articulation when they have deep pockets and extra elastic. A single king flat sheet or duvet can span both halves for a unified look. Leva Sleep's split-specific bedding described above solves this with extra elastic, deep pockets, and duvet clips that hold at full elevation.

How Much Does Split King Delivery And Setup Cost?

Threshold or curbside delivery is typically free from most retailers but leaves all assembly to the buyer. White-glove delivery and setup costs vary by retailer and configuration. Mattress Firm's adjustable base setup service is priced at $159.99 and includes base assembly and carrying up to five flights of stairs. Leva Sleep provides in-house white-glove delivery and setup for a fee, with current pricing available on the Leva Sleep site. Third-party in-home setup services start around $265 from some providers. The total cost of a DIY setup should account for the buyer's time, a helper, and old-bed disposal, which can approach or exceed white-glove pricing when calculated honestly.

Can You Still Cuddle On A Split King?

Yes. The two mattresses sit flush at the surface when both bases are flat, and the center gap is small enough that most couples do not notice it when lying together. The independent articulation only matters when one or both partners adjusts their position. At that point, each side moves independently without disturbing the other. Couples who want to cuddle simply keep both sides flat, which is the default position for both bases.

Conclusion: Making A Split King Work In Your Home

A split king is two separate beds that must be made to behave as one. The delivery path, whether DIY threshold or white-glove, determines how much of that work falls on the buyer. The setup decisions, including how the halves are joined, how remotes are synced, and whether mattress thicknesses match, determine how well the bed works in the first 30 nights.

The post-delivery layer is where most split king problems begin and where many competitor guides stop. Base drift, remote sync loss, center ridges from mismatched mattresses, and sheets that pop off at elevation are common first-month experiences for buyers who were not told what to expect.

Leva Sleep focuses on adjustable beds and handles delivery, setup, and the split-king-specific details generalists often miss. In-house white-glove delivery by Leva's own trained team, the comfort guarantee described above, a wide range of adjustable base models, and bedding engineered for movement at full elevation work together to create a split king that performs as intended.
